2 RCM - Threaded Liquid Flowmeter The RCM is a differential pressure direct reading flowmeter. It is suitable for monitoring all liquids and gases that have low or medium viscosity, low solids content, and are compatible with the materials of construction. The meter features rugged, compact construction. In liquid applications of 6 GPM and higher, pulsation snubbers are incorporated into the connecting pressure passages to produce smooth meter operation independent of pipeline turbulence. This meter was developed for industrial flow metering applications in which durability and reliability are important considerations. Accuracy, small size, low cost, minimal maintenance and resistance to accidental damage are the prime goals in the RCM design. Typical applications include: lube oil and cooling water monitoring, blending processes, reverse osmosis systems, and compressed air measurement. The RCM is available with a 4 20 ma output for interfacing with remote displays and controllers. Limit switches are available to provide high and low limit signals. A Hz frequency output is available to drive frequency based controllers and counters. Specifications Accuracy: ± 3% Full Scale Flow Media: Liquids and Gases Mounting: Horizontal or Vertical Media Temperature Range Standard: - 30 to 212 F Optional: - 80 to 350 F (without electrical options) Maximum Pressure Standard: 180 PSIG Optional: 400 PSIG Housing: Polycarbonate UV stabilized Body: Bronze, Monel, or 316 SS Option -ES: also Teflon TM Bellows: Bronze, Monel 316 SS or Inconel TM Movement: Bronze or SS Seals: Buna-N, Viton, EPDM or Teflon TM Crystal: Polycarbonate Relay : High/Low Alarms Output : 4 20mA Hz Frequency Model RCM-7126

We recommend that valving, if required, be installed downstream of the flowmeter. The gas flow meters (Models 6000 and 9000), are inlet pressure sensitive. To operate properly, the gas pressure at the inlet of the meter must be regulated to a constant, user-selected value. S5
